Craies on Legislation is a standard work on the effect and interpretation of legislation. It provides detailed guidance on assessing legislative intention and is a key reference tool for lawyers who have to administer, advise, argue or adjudicate on Acts of Parliament and statutory instruments.

It is a work of direct practical use for barristers, solicitors and the judiciary. It steers them clearly through a range of critical issues, such as the interpretation of words, what may and may not be implied if the meaning is unclear, what sources of information outside a statute may be used to throw light on its meaning, the effect of new legislation on existing law and the effect of an error in legislation.

The previous edition has been regularly cited by Parliamentary joint committees and relied on in prominent cases. The new 10th edition considers all recent developments in the law.
